The XSPEC laor2 model: accretion disk with broken-power law emissivity profile, black hole emission line.
xslaor2 The xslaor2 model is an additive model component.
The model is described at  .
Deprecated in Sherpa 4.10.0
The ring and routg parameters have been renamed to rin_g and rout_g respectively to match the XSPEC definition. The names ring and routg can still be used to access the parameters, but they will be removed in a future release.

The attributes for this object are:
|lineE||The rest-frame line energy, in keV.|
|Index||The power law dependence of emissivity (scales as R^-Index).|
|Rin_G||The inner radius, in units of GM/c^2.|
|Rout_G||The outer radius, in units of GM/c^2.|
|Incl||The disk inclination angle, in degrees. A face-on disk has Incl=0.|
|Rbreak||The radius at which the emissivity power-law index changes.|
|Index1||The emissivity power-law index for r>Rbreak.|
|norm||The flux in the line, in units of photon/cm^2/s.|

CIAO 4.14 comes with support for version 12.12.0 of the XSPEC models. This can be checked with the following:
% python -c 'from sherpa.astro import xspec; print(xspec.get_xsversion())' 12.12.0
